CONVEYER.

SPECIFICATION forming' part 0f Letters Patent N0. 699,278, dated May 6, 1902.

Application filed August 23, 190i- Serial No. 72,993. (No model.)

To all whom it may concern/.-

Be it known that I, ROLLAND A. ZwoYER, a citizen of the United States, and a resident of Portsmouth, in the county of Newport and State of Rhode Island, have invented certain new and useful Improvements in Conveyers, of which the following is a specification.

This inventio'n'relatesv to conveyors; and its object is the production of conveyors with selfdumping buckets and with which the material conveyed can be transferred from one bucket to another without spilling, thereby enabling the buckets to carry the material in different horizontal planes and directions without resortingto suspension-rods for the buckets.

Figure lshows a fragmentary front elevation of my conveyer.

tion of a modification of my conveyer on a line mof Figfl. Fig. 4 shows a top view of Fig. 3. Fig. 5 represents a perspective View of one of the buckets. Fig. 6 is a perspective view of a modified form of bucket.

Referring to Figs. 1 and 2, tracks A A' are shown supporting the rollers B, to which are -journaled the linked drive-chains D, the latter carrying the buckets E. Sprocket drive- Wheels F on axles H are geared with the linked drive-chains, and the said vchains also turn over guide-wheels F', supported on axles H. A curvedlcover G is securedover the wheels F and sufficiently distant therefrom to allow the ends of the buckets to just clear the inside face of the said cover. The buckets are of special construction and comprise a central platform c, with sides e2 e3, extending from both sides of the platform, and ends e, the latter extending only from one side ofthe said platform, between the sides of the buckets. buckets to clear thedrive-chains.

Thelinked drive-chains D consist of the in side links d and outside links d, connected with bolts d2, carrying the ferrules d3. Journal-pins d4, with ferrules d3, carry the rollers B and also constitute bolts for the linked driveechains'and secure the buckets to the said chains, one ofthe said journal-pins and an adjacent bolt of the linked drivechain supporting each side of each bucket.

The ends of the axles H H may be supported in journal-bearings in the usual way, and a Fig. 2 is a plan View of.A Fig. 1. Fig. 3 represents a partial vertical sec- The sides e3 narrow the bodies of the' driving-pulley H2 is shown secured on ythe axle H, although a sprocket-wheel, gear, or other means could be substituted.

In the operation of the conveyer its novel features will become apparent, and for the purpose of demonstrating'its novelty the position of the buckets just after engaging with the wheels F is designated with the letter E', and'during its contact and travel with the said sprocket drive-wheelv it is turned bottom side up and assumes a position, as E2, the effect of which turning will discharge the material from the bucket E into the bucket E2 without spilling, the material being carried on one side of the central platform in the upper row of buckets and on the opposite side in the lower row. The ends e4 of the buckets `prevent the material escaping when flowing from one bucket to the other, but do not interfere with its escape when dumping, as shown atv E3, over the guide-wheels F. It will be seen that the journal-pins d4, which lock the rollers, the links of the chain, and the buckets, are in about the central portion of the said buckets and that the bolts adjacent, which also secure the buckets, are near the ends thereof, by virtue of which disposition the buckets are tipped, as shown at E', E2, and E3. The cover Gis added as a further means-to prevent the spilling of the Inaterial when it is being transferred from one bucket to another. To propel the conveyer, power is applied to the axle H, and the conveyer buckets will automatically transfer their charges when over the guide-wheels F from one bucket to its adjacent bucket, and the contents of the buckets will be dumped or emptied when they turn over the guidewheels F. Referring to Figs. 3, 4, and 6, the buckets E5 are shown without any ends, as e4, Figs. 1, 2, and 5. The buckets consist of the central platforms e5, the ends of which, as e, butt against each other when the said buckets are propelled in straight lines and are suficiently close when turning with the sprocket drive-wheels F to prevent any of their contents to escape between their ends, as shown at E4 and E6. Sides el', with sloping ends es, extend on both sides of the central platforms e5.

The remaining features of the conveyer are IOC similar to the appurtenances shown in Figs. l and 2.

Having described my invention, I desire to secure by United States Letters Patent and claim l. A couveyercomprising,bucketsprovided with a central platform in each bucket, sides extending above and below the said platform, an end projecting from the platform of each bucket and joining the side thereof, rollers journaled to the buckets; linked drive-chains pinned to the buckets, sprocket drive-wheels geared with the linked drive chains, and guide-wheels for the latter.

2. Aconveyercomprising,bueketsprovided with a platform in each bucket, sides extending above and below the platform, an end eX- tending from one side of the platform and joining the sides at one end of each bucket, rollers journaled to the buckets, linked drivechains, two of the connecting-pieces of the chain journaled to each side of each bucket, sprocket drive-wheels geared with the linked drive-chains, and guide-wheels for the buckets.

3. Aconveyercoinprising,buckets provided with a central platform in each bucket, sides extending above and below the platform, journal-pins extending from the central portion of the buckets, drivecl1ains and rollers journaled with the said pins, a bolt extending from one end of each side of the buckets and journaled to the drive-chains, sprocket drivewheels geared with drive-chains, and guide- Wheels for the said chains.

4. A conveyercomprising,buckets provided with a platform in the central portion of each bucket, sides extending above and below the said platform, an end joining the sides on one side of the platform, linked drive-chains, rollers supporting the linked drive-chains, a pin connecting the rollers, chain and buckets in the middle portion of the buckets, a bolt connecting the linked chain with the end of a bucket, sprocket drive-wheels, and guide- Wheels operating with the linked chain, a curved cover extending over the drive-wheels, a sufcient distance therefrom to clear the buckets.

5. Aconveyercomprising,buckets provided with a central platform in each bucket, sides extending above and below the platform, journal-pins extending from the central portion of each bucket, drive-chains and rollers journaled with the said pins, a bolt extending from one end of each side of the buckets and journaled to the drive chains, sprocket drive- Wheels geared with the drive-ch ains, a curved cover extending over the drive-Wheels, and a sufficient distance therefrom for the clearance of the buckets, guide-wheels for the buckets, and tracks for the rollers.
